General

The Body Control Module (BCM) is capable of accomplishing multiple body control functions Components directly connected to the BCM are controlled by the BCM's outputs. The BCM controls the outputs based on the following information:
^ The input information obtained from the sensors and the switches that are directly connected to the BCM
^ Borrowing information from other vehicle systems that are connected to the Class 2 serial data link

The BCM evaluates this information and controls the certain body systems by commanding an output on or off.

The BCM is also capable of commanding other vehicle systems to control functions that are not directly wired and/or controlled by the BCM. The BCM accomplishes this task by sending specific messages on the Class 2 serial data link. The vehicle system capable of performing such function will respond to the BCM message.

The BCM performs the following functions:
^ Retained Accessory Power (RAP)
^ Audible warnings
^ Interior lighting
^ Automatic power door locks
^ Keyless entry
^ PASS-Key (R) II theft deterrent
^ Trunk release
